The pinion 10 fast on shaft 3' and meshing withthe flywheel 2 reduces the speed of the reverse motion.

The movement of the driving shaft 1 is transmitted to the rear'axle 30 (Fig. 10) by the bevel pinion 7 fast on the end *of the shaft 6 and which engages with a. wheel 31 with corresponding teeth, fast on" said shaft. Wheel 31 is enclosed and turns freely in ball hearings in a casing 32 (Fig. 9).

" If,".on'the contrary, the lever 19 isbrought:

into its extreme rear position, the plate 17 declutches the sleeves 11a, 11b and engages the sleeves 12a,12bof the lay-shaft 3, 3 which receives in this case its rotation'from the driving shaft l'through the toothed wheel 8, this movement beingtransmitted to it in Flywheel 2 being rigid with" shaft 6 likewise turns in reverse direction corresponding to reverserunning, at reduced speed. This reversal ofmovement can be effected rapidly andvery smoothly by reason of the disposition of'the clutching and declutching mechanisms'of one or. other of the sleeves and of the operating lever 19. V

The driving shaft 1 and lay-shaft '3 are mounted in thrust bearings 33- ("Fig.' 11) suitably disposed on the cross members 34, 35 which connect the two longitudinal members of the chassis frame. The rearcross member 35 has a recess 36 for the passage of the flywheel 2 which is enclosed in the easing 37 :(Fig. 6) secured below the cross member 85. 7

Finally reinforcing bars 38 are secured in brackets 39 and housings 4O formed on the casing 32. I Y

Said bars consist of two parts resiliently connected together by means of coiled springsheld in place byscrews.

The steering wheel 41, the lever pedal 28 are arranged in the usual manner near the seat 42 (Fig. 12) of the driver.
